Using IP Network Multipathing on a Solaris System With Zones Installed

How to Use IP Network Multipathing in Exclusive-IP Non-Global Zones

IP Network Multipathing (IPMP) in an exclusive-IP zone is configured as it is
in the global zone.

You can configure one or more physical interfaces into an IP multipathing group,
or IPMP group. After configuring IPMP, the system automatically monitors the interfaces in
the IPMP group for failure. If an interface in the group fails or
is removed for maintenance, IPMP automatically migrates, or fails over, the failed interface's
IP addresses. The recipient of these addresses is a functioning interface in the
failed interface's IPMP group. The failover feature of IPMP preserves connectivity and prevents
disruption of any existing connections. Additionally, IPMP improves overall network performance by automatically spreading
out network traffic across the set of interfaces in the IPMP group. This
process is called load spreading.
